Product Description

The A9F74116 is a 1-pole (1P), 16A miniature circuit breaker (MCB) from Schneider Electric’s Acti9 iC60N series. Utilizing thermal-magnetic trip technology with a Type C tripping curve, it provides dual overload and short-circuit protection for single-phase AC circuits. It incorporates Schneider Electric’s VisiSafe visible isolation strip and VisiTrip fault indicator for visual safety and maintenance diagnostics.

Product Parameters

Product Advantages

• VisiSafe Visible Isolation: The green status band guarantees physical opening of main contacts, allowing safe downstream maintenance according to IEC/EN 60947-2.
• VisiTrip Red Indicator: Front mechanical flag immediately pinpoints the tripped circuit upon fault detection, reducing troubleshooting downtime.
• Independent Fast-Closing: Internal mechanism closes contacts independently of toggle handle speed, minimizing arc erosion and extending operating life.
• Compact 1P Footprint: Takes up only 18 mm of DIN rail width to conserve enclosure space in crowded control cabinets.
• Energy Limitation Class 3: Limits peak pass-through fault energy during short circuits, protecting downstream cables and devices from thermal stress.

Important Considerations and Precautions

• C-Curve Trip Profile: Optimized for general commercial and light industrial branch loads (lighting, receptacles, small appliances). For heavy motor loads with high startup surges, consider a D-curve breaker.
• Terminal Screw Torque: Tighten tunnel terminals to the recommended torque spec (2.0 N·m to 3.5 N·m) to prevent loose-wire thermal hotspots.
• Enclosure Rating: Carries an IP20 rating; install inside a distribution panel or enclosure rated IP54 or higher for outdoor, dusty, or high-moisture environments.
• No Earth Leakage Function: Protects strictly against overloads and short circuits. Add a Vigi iC60 residual current block (RCD) if earth leakage protection is required.

Product Applications

• Single-Phase Branch Lighting & Outlets: Overload and short-circuit protection for standard 230V lighting and receptacle circuits.
• Control Cabinet Auxiliary Power: Protecting 230VAC primary feeds for 24VDC power supplies and PLC rack supplies.
• Commercial HVAC Controls: Protecting single-phase air handlers, small fan coils, and actuator control lines.
• Building Sub-Distribution Boards: Branch protection in commercial office spaces, schools, and residential units.
